468 viewsI placed a friction plate back in to measure the gap. I had to use an Allen wrench: 2.5mm. Not good. Max gap is supposed to be no more than 0.6mm!

458 viewsThis is the outer-most friction plate and driven plate. The average thickness of the friction plates was ~2.8mm. They should be replaced if they are less than 3.2mm!

422 viewsThese are the inner-most plates. Only slightly less wear than the fronts.

476 viewsAnother view of the same worn teeth.

470 viewsSince I wouldn't be using any of my original plates I used one as a lock to hold the clutch drum so I could remove the center retaining bolt.
IMAG0844.jpg
466 viewsHere's how the clutch basket looked. Those streaks are LOTS of thread locker applied at the factory. It leaked out the back side as well. After removing the eight retaining bolts I had to use a drift and tap a couple of the ears on the basket to gently break it free.
